my front window is not showing any images.

Your heads up display has an adjustment wheel on the left side of the steering wheel on the instrument panel. It might be out of adjustment. If you rotate the wheel up and down you will adjust the viewing angle. It might be adjusted too far one way or another.... Try that first.

if that doesnt work look up through your stearing wheel when its on (i know its uncomfortable) if u see it then a small arm inside your HUD has worn through the small peice that holds it together. it take about 4 hours and some sort of epoxy to put it back into working shape. you can find the step-by-step on google.
